Thanks, guv1976.
That is the site I was referencing in my previous reply. It shows that there are specific requirements for AC access if my OWE status is the result of AS status. (Sorry, I didn't realize that AC was the acronym for Admiral's Club - that was the cause of my previous confusion because, as I said, I'm new to AA.) What I've learned is that if you are using AS MVP Gold 75K to establish OWE status, then you must be flying on specific itineraries in order to get AC access. These include US to Asia, Australia, Central America, Europe, New Zealand, or South America. There are also some transcon flights which qualify as well but flights to the Caribbean, of which Curacao is part, do not qualify. Long story but I figured it out...I won't have access per the specific rules. My guess is that it must have something to do with reciprocal lounge access agreements between AA and Alaska Air.

Based on the advice from the members here, I've replaced my AA FF# with my AS FF# and that should get me the rest of the OWE benefits for my flight. I'll just have to throw away the miles because I won't likely have an opportunity to use them on AS in the future.

Thank you all for your feedback. It was helpful.
